Out-of-Bounds Affecting torvalds/linux package, versions [6.10,6.18.51)[6.19,7.2.5)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Upgrade torvalds/linux to version 6.18.51, 7.2.5 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds in the panthor_fw_read_build_info function. An attacker can cause the kernel to read out-of-bounds memory by supplying a crafted firmware image with manipulated metadata fields, leading to potential disclosure of adjacent kernel memory and denial of service through kernel oops or panic during GPU probe. This is only exploitable if a malicious firmware blob is placed in the local firmware search path accessible to the system before driver probe.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
